"I love my coaches across the board, love those two guys in particular," Manuel said. "I'm extremely pleased with where we are from a staffing, coaching standpoint and Jim and John are two people that I would love to see retire from this institution, retire from coaching.?

"Jim ... knows how I feel about him. We've had great conversations and I don't want him to go anywhere."

Harbaugh, 54, is 28-11 as Wolverines coach. He's entering the fourth season of a seven-year contract he signed in December 2014.

Harbaugh's original deal called for $5 million a year in salary, but with bonuses and $2 million in life insurance, his total compensation in 2016 was $7 million, third highest in the country behind Alabama's Nick Saban and Clemson's Dabo Swinney, and just ahead of Ohio State's Urban Meyer.

Manuel said he is in the process of finalizing a new contract for Beilein, who took the Wolverines to the national title game this season.

Beilein, 65, makes $3.37 million a year on a contract that extends through 2020-21. That put him ninth nationally, and third in the Big Ten behind Ohio State's Chris Holtmann and Michigan State's Tom Izzo.
